Heres what I did on my plastic dash,
Cleaned with TSP cleaner.
Sprayed with adhesion promotion from dupli color
Sprayed 5 coats of the black vinyl and fabric

Everytime in the same spot it leaves a worn out/sun spot look.
There were no spots until I used the TSP cleaner. Should I sand it a little or spray some primer or strip it down and clean it again? I'm not sure what to do with it to get it even.

What did Duplicolor recommend to use for initial cleaning? Did you scuff it a little with a Scotchbrite pad while you were cleaning it? If you clean the plastic, you clean it until water won't bead up on it, then dry it and make sure it's completely dry before you try to color it. You're probably going to have to re-do this piece. This time read and follow all the directions. It's just like painting anything, the preparation is more important than the painting.

Well of course the recommend clening with their product, but I was told that most cleaners wont remove the chemical to break the plastic out of the mold that they use in the factory and to use TSP. I did not scuff it up because its a textured plastic and I assuemed that cleaning it and using the adhesion promoter that would be fine. I didnt want to ruin the texture. when you say redo what do you mean? would primer over top and new paint work or will I have to sand or strip it? I dont want to ruin the texture or plastic.

well right off the bat you used a cleaner that someone told you to use, Why on earth would you not follow the MFG's directions ? also a textured finish has grooves in it that need to be scrubed cleaned.

I did scrub it with a stiff bristle brush, I cleaned it let it dry completly, cleaned it again. I dont see how a cleaner really makes a difference if all it does is remove chemicals. I know for a fact standard cleaners for dust and grime wont remove the UV resistant coatings/release agents.

Doesnt matter what I did, I just need to know how to get a spot to cover\

Yes, they tell you to clean it with their products because they know that they'll work. You want to know why this particular piece failed, and I'm telling you that if the manufacturer didn't call for it to be cleaned with TSP then you're probably going to have problems with it until you strip it back down and start over. If you didn't follow instructions and use the products recommended you are basically doomed to failure. The paint guys will tell you not to substitute anything else for what the manufacturer recommends, why would it be any different with plastic? If you change a recipe from sugar to salt because they are both granulated and white what will happen?

It is a bit hard to give a suggestion without seeing the spot.

Now that the paint has dried I would try a light coat, blending across the spot only and see if there is coverage. Dont put it on wet. If it starts to cover repeat when dry, then if it is covered spray the whole part again with 1 or 2 medium coats.

If Duplicolor is anything like SEM, it is not a paint it is a flexible coating that is drawn right into what you're coloring. If the surface is not completely clean to begin with, the spot will keep coming back until the original surface is fixed.

ok so I contacted Dupli color and holy ****..... you can use TSP like I said. So please stop acting like im stupid for using it when you know nothing about it yourself.

Thank you for contacting Dupli-Color. We appreciate your inquiry.

Because of the wide variety of plastics used in the automotive industry, we can not recommend a specific preparation system. However, the following guideline may be followed:

Congratulations, genius. I didn't say it was wrong to use TSP, I asked you if THEY recommended it, not some guy you know. I also asked you if you scuffed it with a Scotchbrite pad to which you answered NO. Did you use their adhesion promoter or something some guy told you to use? Instead of taking offense, why don't you LISTEN when people are trying to help you? You didn't follow the directions so now you get to do it over. What did they tell you was the problem, or were you too embarrassed to ask? I don't know what I'm talking about? I do car interiors for a living, and I've never had the problem you have. Go somewhere else and ask other geniuses like you what you did wrong if you think you're getting bad advise, although you seem to thrive on bad advise..
